For decades, scientists could describe the peopling of the Americas only in broad strokes, leaving plenty of mysteries about when and how people spread across the continents. Now, state-of-the-art ancient DNA methods, applied to scores of new samples from around the Americas, are filling in the picture. Two independent studies, published in Cell and online in Sciencefind that ancient populations expanded rapidly across the Americas about 13, years ago.
The remains of a boy from palaeolithic Siberia — shown here in a burial reconstruction at the Hermitage Museum in St. Petersburg — revealed that he had European genes. The results show that people related to western Eurasians had spread further east than anyone had suspected, and lived in Siberia during the coldest parts of the last Ice Age.
While half a parent's DNA is passed down, that parent's ethnicities are not passed down in halves. North and South America were settled by at least three waves of migrants from Asia, who occupied the Americas from Canada to the southern tip of Chile. North America was initially occupied by people who came from Siberia and coastal North Asia.
Although the primary purpose of the Book of Mormon is more spiritual than historical, some people have wondered whether the migrations it describes are compatible with scientific studies of ancient America. The discussion has centered on the field of population genetics and developments in DNA science. Some have contended that the migrations mentioned in the Book of Mormon did not occur because the majority of DNA identified to date in modern native peoples most closely resembles that of eastern Asian populations.
A skeleton in Siberia nearly 10, years old has yielded DNA that reveals a striking kinship to living Native Americansscientists reported on Wednesday. The finding, published in the journal Nature, provides an important new clue to the migrations that first brought people to the Americas. Decades of research by archaeologists and linguists suggests that people first came to the Americas at the end of the last ice age, by 14, years ago.
The findings were published today January 3 in Nature. Researchers usually agree that humans arrived in the Americas through Beringia—the area encompassing parts of present-day East Asia and North America, connected by what was the Bering Land Bridge. But the scientists must rely on inferences from both archaeological and genomic data to figure out how and when this migration occurred.
Scientists are analyzing ancient and modern DNA to learn more about how people first colonized the Americas. Pictured here: tools discovered in at a Clovis-era burial site in western Montana, alongside remains of a boy who died more than 12, years ago, known as Anzick This week, two teams of scientists released reports detailing the origins of Native American peoples. Both groups looked at ancient and modern DNA to attempt to learn more about the movements of populations from Asia into the New World, and about how groups mixed once they got here.
Currently 23andMe has several features that can reveal genetic evidence of Native American ancestry, although they are not considered a confirmatory test or proof of such ancestry in a legal context. The Ancestry Composition report estimates what percent of your DNA comes from each of 45 populations worldwide, reaching back about years. It also tells you about your connection to different Recent Ancestor Locations, which are specific countries where one or more of your ancestors likely lived within the last years.
